Subject: [PATCH] devproc: remove pgrpid == 1 check for notepg open

assuming that this check tried to prevent the hostowner
from killing init, it is silly because init would just
handle the note.

with kbdfs, we actually want to send interrupt note to
the initial process group so instead of working arround
this with rfork(RFNOTEG|RFNAMEG), we remove the check.
